Heat season runs from October 1st to May 31st. This year there are new regulations governing the temperatures at which building owners are required to provide tenants with heat. During the day, from 6 a.m. – 10 p.m., landlords are required to keep a minimum temperature of 68 F when the outside temperature is 55 F or below. At night, from 10 p.m. – 6 a.m., landlords are required to keep a minimum temperature of 62 F at all times. Tenants without heat should file a complaint by calling 311.
